Which outcome results when hydraulic action on loess?

💡 Explanation

Gullies form because loess's loosely packed silt is vulnerable to erosion by hydraulic action, leading to vertical incision of the landscape (gullying), therefore gullies result, rather than silica cementation due to the lower clay amount.
